FONDDU LAC prefixes in area code 920
NANPA records 34 assigned NXX blocks to rate center FONDDU LAC in area code 920, 4.3% of the 785 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 14 holders hold those blocks, the largest being WISCONSIN BELL INC (9), UNITED STATES CELLULAR - WI (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (4). The earliest assignment on record here is 2001-02-05 and the most recent 2024-02-28. 24 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
